Key Technical Advantages:

High-Precision Extruded Aluminum Housing: Crafted from high-strength aerospace-grade aluminum alloy, the housing provides exceptional strength-to-weight performance. Internal flow channels are CFD-optimized to reduce fluid resistance and operating noise.
Bimetallic Floating Side Plates: Internally equipped with auto-compensating side plates that dynamically adjust gear side clearances based on system pressure, maintaining volumetric efficiency above 90% even under peak load.
High-Precision Gear Grinding: Utilizing advanced CNC hobbing and grinding, we achieve superior tooth-mesh overlap, significantly reducing vibration and pressure pulsations to protect your system from pulse-induced shocks.
Wear-Resistant Composite Bushings: Critical shaft support utilizes special wear-resistant alloy bushings with self-lubricating properties, maintaining oil film integrity under harsh conditions and drastically extending the service life of the pump.

Application Areas:

Agricultural Machinery: Tractor steering assist pumps, seeders, and grain elevator power sources.
Municipal Vehicles: Hydraulic lift systems for small dump trucks and refuse collectors.
Industrial Auxiliary: Small Hydraulic Power Units (HPU) and material handling cart power.

Expert Maintenance Tips:

Fluid Cleanliness Standard: Gear pumps are highly sensitive to contamination. Ensure hydraulic fluid meets ISO 4406 19/16/13 standards and replace return-line filters regularly to prevent particulate matter from scoring gear tips.
Suction Seal Integrity: Ensure there are no air leaks at the suction port during installation. Even minor air ingestion can cause cavitation within the gear pump, leading to rapid surface erosion.
Temperature Management: While aluminum pumps have good heat dissipation, prolonged operation above 80°C will cause seal degradation. Ensure your system has adequate cooling capacity to maintain the pump within its optimal temperature range.
